Hello there ,

Hope you are doing well . See, if your preparing for NEET and want to practice biology mcqs,I'll recommend to you the MTG NCERT at fingertips book ,it has sufficient number of good quality questions which will clarify all your concepts . Another online platform from where you'll get excellent quality biology mcqs is from the Neetprep platform i.e. the Masterclass in Biology by Dr. N.K. Sharma . This will covers questions containing concepts from every nook and corner of Biology NCERT 11th and 12th textbooks . These are according to me the best sources from where you can practice Biology MCQs to have a strong base and not miss out on anything.

Hope my answer helped.
